9 Claims.

The invention relates, in general, to improvements in electrical vaporzers and more particularly to an electrical combination lighting unit and diffuser embodying novel structural features to afford ready disbursement of fumes.

An object of the invention is to confine, within a lighting unit, a diiusible substance of a character which will emit fumes when the lighting unit is in use.

Another object of the invention is to provide u a combination lighting unit and diffuser, the latter of which is effective to emit fumes only when said unit is lighted.

Another object is to provide an electrical combination lighting unit and diffuser the structure of which is such as not to impair the efficiency of the lighting unit.

Another object is to provide an electrical cornbination lighting unit and diffuser which is not expensive to manufacture and which embodies the general appearance of a conventional electrical lamp bulb.

The foregoing and such other objects of the invention as will appear hereinafter as lthe description proceeds will be more readily understood from a perusal of the following specification, in which reference is made to the accompanying drawing, wherein:

Fig. 1 is a longitudinal central sectional view, partly in elevation, of the unit.

Fig. 2 is an enlarged fragmentary detail sectional view of the base portion of the unit shown in Fig. 1.

Referring particularly to the disclosure in the drawing, the glass bulb A may be of any practicable shape but preferably is shaped like a conventional electrical lamp bulb and has a reduced diameter at one end formed with an inwardly extending terminal support E. The support E carries the usual live and ground wires D, the inner free ends of which are electrically connected to the usual filament C, within the bulb. When electric current is supplied to the wires D the filament becomes heated and throws off the required glow for lighting purposes.

'Ihe filament support E has an axial recess G extending inwardly from its outside end for a purpose to be more fully explained hereinafter. A tube H, formed integral with the closed end of the support E, communicates with the interior of the bulb and extends into the recess G. The bulb A is partially evacuated through this tube and the tube is then sealed by pinching its lower end together as shown. A conventional threaded connection base K is fitted over the reduced end of the glass bulb A and the two members are joined by a suitable cement J. The cement J preferably is applied in a plastic state and when dry shrinks sufciently to draw slightly away from the connection base so as not to hermetically seal this connection. The cement is thus tightly bound to the bulb and the connection base cannot readily be removed because of the opposed threaded surfaces of the cement and connection base.

As shown, the connection base K extends a short distance beyond the end of the glass bulb A and has an internal flange upon which is seated the usual insulation block M having a central opening through which one of the wires D extends. The other wire D preferably follows the contour of the recessed end of thev glass bulb and is bent over the outside of the connection base K and soldered or otherwise joined thereto to provide an electrical connection therewith.

It will be observed that this structure defines a compartment P which is in direct. communication with the recess G in the filament support. The chamber thus provided is l'llled with a suitable diiusible substance Q, which may be in the form of a powder, a compound or a liquid, such as for example a deodorant, chemical, disinfectant, perfume, medicine or the like. This diffusible substance is initially admitted into the chamber through the axial opening in the insulation block M and said opening is closed by a contact plate electrically connected to the projecting end O of one of the wires D. 'Ihe hollow tubular terminal support provides a glass division wall between the partially evacuated interior of the glass bulb A and the chamber G-P.

When the unit is screwed into a conventional electrical outlet and electric current applied thereto, the lament C becomes irradiant and the resulting heat is transmitted through the wall of the filament support E to the diffusible substance Q. Upon being heated, the diffusible substance emits fumes, the greater portion of which escape through the restricted annular opening between the cement J and the connection base K. Fumes also escape through the spaces L and N (best shown in Fig. 2) separating the insulation block M from the connection base K and from the associated contact plate respectively. Due to the restricted area of the annular opening and the spaces L and N, the diffusible substance cannot at any time escape from the chamber.

Since the rate of diffusion is dependent upon the degree of heat applied to the diffusible substance, it is evident that the rate of diffusion is readily controlled through the selection of a unit of high or low wattage. As shown the electrical vaporizer will have the general appearance of a conventional electrical lamp bulb and may readily be screwed into any standard electrical outlet.
